WPF Datagrid-不显示任何滚动条 [英] WPF Datagrid - Not showing any Scrollbar

问题描述

我的Datagrid在ObservableCollection上具有绑定，并在对EF提取的某些值进行分组后被填充.

My Datagrid has a binding on an ObservableCollection and gets filled after grouping some values fetched by EF.

我的问题是，datagrid-height超出了窗口大小. 有人知道如何解决该问题吗...我差点把自己用谷歌搜索死了..:o

My Problem is, that the datagrid-height grows beyond the window size. Does anyone know how to get that fixed... I almost googled myself to death.. :o

推荐答案

总而言之，您的控件看起来不错，这表明问题出在视觉树的上方.它很可能是InventoryList或它的父级之一，处于受控状态，可以为其子级提供无限量的空间来生长，例如StackPanel，ScrollViewer或Canvas.因此，DataGrid可以增长以容纳所有项目，因此看不到滚动条.

To sum up comments your control looks fine which would suggest that the problem is somewhere up the visual tree. Most likely InventoryList, or one of its parents, it's placed in control that gives its children infinite amount of space to grow like StackPanel, ScrollViewer or Canvas. Because of that DataGrid can grow to accommodate all item hence not scroll bar is visible.

删除该控件或将其替换为限制其子控件大小的控件

Remove that control or replace it with one that limits the size of its children
